SPRING-BOARD WAGON.

. SPECIFICATION forming part of Letters Patent No. 441,191, datedNovember 25, 1890. I Application tiled September 2, 1889.` Serial No.322,732. (No model.) y l .To all whom it may concern:

Be it known that I, JAMES K. P. PINE, of the village of Lansingburg,county of Rensselaer, and State of New York, have invented new anduseful Improvements in Spring-Board lVagons, of which the following is aspecifica tion.

My invention relates to improvements upon that class of spring-boardwagons in which combined metal springs and spring-boards are used andupon which the wagon-body is supported and the object and purpose of myinvention are to render'the movement of the wagon box or body moresteady, which better result I accomplish by dispensing with thecross-bar heretofore applied to connect the spring-boards where crownedand to separately connect the body with the metal springs and thespring-boards, as will be more fully detailed hereinafter in connectionwith the illustrations of the parts.

Accompanying this specication, to form a part of it, there are twoplates of drawings containing four figures illustrating my invention,with the same designation of parts by letter reference used in all ofthem.

Of the illustrations, Figure 1 is a perspective of the runninggear of awagon containing my invention with the body removed and with thespring-boards shown as placed outside of the metalV springs. Fig. 2 is asection taken on the line as so of Fig. l. Fig. 3 is a perspective of awagon-gear containing my im' provement and in which the metal springsare arranged outside of the spring-boards. Fig. 4 is a section taken onthe line .t2 Q02 of Fig. 3.

The several parts vof the apparatus thus illustrated are designated byletter reference,

and the function of the parts is described as follows:

The .letter A designates the front axle; A2, the hind axle 5 H, thehead-block; K, the kingbolt; VW, the fifth-wheel, all of which parts areof the usual and ordinary construction.

The letters B designate two spring-boards, the ends of which are madeflat, as indicated at e, and each of these boards between these iiatends is made to curve or crown upwardly and centrally, as indicated atC. The fiat ends of these boards oppositely connect at the front withthe head-block and at the rear with the hind axle at a.

The letter b designates a cross-bar arranged upon the lower surface ofand connecting the two spring-boards near where they join thehead-block, and b2 a cross=bar arranged upon the lower surface and whichconnects the two spring-boards near the hind axle.

The letters S designate two leaf-springs, each of which has its frontend resting on the cross-bar b and its -rear end on the cross-bar b2.Between their ends these leaf-springs are made to curve upwardly at U.

The letter R designates a riser or plate that is arranged upon each ofthe springs S where upcurved at the top, and each of these risers orplates is adapted thereat to connect with the wagon-body.

The letter D2 designates bolsters or risers that are attached to theupcurved and crowned tops of the springboards, each of which is thereatadapted to connect with the each of the springs and each of thespringboards separately connect with the wagonbody in the samehorizontal plane.

E is the body.

As heretofore used, similarlyarranged leaf-springs, with thespring-boards placed side by side between the metal springs and with theends of the latter inserted and held in keepers constructed on the outerends of slats that were arranged on the under side of the boards toconnect them thereat. In this older device the boards where crowned wereconnected by a cross-bar that at each side passed out under theleaf-springs, and on the end of which cross-bar where subtending thespringboards lthe metal springs rested, with the wagon-body connected tothe latter alone, so that when the body was weighted down the metalsprings were engaging with the ends of the cross-bar operated upon theboards.

By my improvement risers or side bolsters are used at each side toconnect the body with the springboards and metal springs, so that theyoperate together and at the same time to take up any vertical orside-to-side swaying of the body, and. the cross-bar is dispensed with.

spring-boards have been combined with metal `wagon-body. As thus madeand arranged,

IOC

4 By this new arrangement of the connection between the spring-boardsand metal springs I am enabled to use the spring-boards at the inner orouter sides of the metal springs, and in either instance the operationis the samethat is, the boards and metal springs take up connectedly andtogether any vibration communicated to the running-gear when passingover the rough places in the road.

Having thus described my invention, what -Iciaim, and desire to secureby Letters Patent, 1s i 'In a running-gear for spring-board wagons, thecombination, with two spring-boards centrally crowned and resting uponthe headblock at the front and a head-block or hind axle at the rear andhaving cross-bars connecting said spring-boards near their ends, of ametal leaf-spring arranged at the side of each of said spring-boards,and a riser adapted to separately connect each of said springboards andmetal springs with the wagonbody', substantially as and for the purposesset forth. Y

Signed at Troy, New York, this 9th day of February, 1889, and in thepresence of the two witnesses whose names are hereto written.
